Yeah look that's fair.
I don't see Jake beating other good WW's in mma. I just think of anyone, Nate is a good stylistic match up for Jake.
Nate isn't good at any of the potential foil areas for JP.
I can't recall the last time Diaz threw a damaging kick..
Most dangerous place for Jake would be in the clinch and the potential for Diaz to get a standing back take, or just drag Jake to the mat, fight would be over pretty quick then.
JP and his team are very good at strategy and focused training, I think they'd do a decent job at patching up those vulnerable areas.
Plus Nate'll be older, and JP will be closer to his prime..
Just my take.
